Maybe a weird question.

Samantha • I am 26 years old. My husband and I are high school sweethearts and are expecting baby #3 In August!!
This might be a weird or stupid question but I was wondering if anyone knows. With my first child I went into labor but my water never broke until they did it in the hospital my second my water broke at home. I'm curious what are the chances my water will break on its own with the third if it makes a difference that it did with my last or if it's totally random.
